A Quantum Paradox of Choice and Purported Classical Analogues
Emily Adlam, Adrian Kent
We recently considered the task of summoning an unknown quantum state and proved necessary and sufficient conditions for Alice to be able to guarantee to complete the task when the…
A Quantum Paradox of Choice: More Freedom Makes Summoning a Quantum State Harder
Emily Adlam, Adrian Kent
The properties of quantum information in space-time can be investigated by studying operational tasks. In one such task, summoning, an unknown quantum state is supplied at one poin…
Device-Independent Relativistic Quantum Bit Commitment
Emily Adlam, Adrian Kent
We examine the possibility of device-independent relativistic quantum bit commitment. We note the potential threat of {\it location attacks}, in which the behaviour of untrusted de…
Deterministic Relativistic Quantum Bit Commitment
Emily Adlam, Adrian Kent
We describe new unconditionally secure bit commitment schemes whose security is based on Minkowski causality and the monogamy of quantum entanglement. We first describe an ideal sc…
